HPV 18 Positive: Assessment and Follow-up | Şişli, Nişantaşı, Istanbul

What does an HPV 18 positive result mean?

HPV 18 is associated with cervical adenocarcinoma and glandular precursor disease more strongly than many other genotypes. Detection does not mean glandular cancer is present; it changes the level and location of attention during assessment.

HPV 18 positive but Pap smear normal

Current risk-based guidance generally recommends colposcopy when HPV 18 is detected even if cytology is negative. Whether endocervical sampling is appropriate depends on age, pregnancy status, transformation-zone visibility and the referral result.

What if it is positive again?

A later negative result is reassuring, but follow-up still depends on previous cytology, biopsy and treatment history.

How should grouped laboratory results be read?

Some assays or reports may mention 18/45 together. If the laboratory does not separate them, do not assume HPV 18 is negative or that only HPV 45 is present.

Is HPV 18 covered by vaccination?

HPV 18 is included in the 9-valent vaccine. Vaccination is preventive and does not clear an existing HPV 18 infection.

When can colposcopy or biopsy become relevant?

Colposcopy and biopsy decisions are based on the genotype, cytology or dual-stain result where appropriate, previous screening, prior CIN2/3 treatment and the clinical context. HPV genotype alone is not a biopsy diagnosis.
